Features
Global Wear Leveling – Advanced algorithm to enhance the Wear-Leveling Efficiency
Global wear leveling ensures every block has an even erase count. By ensuring all spare blocks in the SSD’s flash chips
are managed in a single pool, each block can then have an even erase count. This helps to extend the lifespan of a SSD
and to provide the best possible endurance.
There are three main processes in global wear-leveling:
1 Record the block erase count and save this in the wear-leveling table.
2 Finds the static-block and saves this in the wear-leveling pointer.
3 Checks the erase count when a block is pulled from the pool of spare blocks. If the erased block count is larger than
the Wear Count (WEARCNT), then the static blocks are leveraged against the over-count blocks.
Bad Block Management
When the flash encounters an ECC, program or erase failure, the controller will mark the block as a bad block to prevent
use of this block and cause data loss in the future.
Advanced Garbage Collection
Transcend’s SSDs have a perfect garbage collection mechanism to help improve performance. Advanced Garbage
collection can efficiently improve memory management to ensure the SSD’s stable performance. With Transcend
advanced flash management, the drive can still keep high performance even after a long operating time.
Enhanced S.M.A.R.T. function
Transcend SSD supports the innovative S.M.A.R.T. command (Self-Monitoring, Analysis, and Reporting Technology)
that allows the user to read the health information of the SSD in a much more efficient way.
Power Shield
The controller uses internal power shield circuit to prevent SSD from being damaged when a sudden power outage
occurs. The SSD’s internal power detection mechanism can monitor power provided by the host. When a sudden power
outage happens, the SSD can execute power shield mechanism to protect data stored on the SSD.
LDPC ECC algorithm
LDPC (Low-Density Parity Check) is a powerful ECC algorithm which offers better quality and reliability in order to keep
your data secure. LDPC mechanism is better for massive data transmission environment.
SLC Caching
SLC caching allows TLC NAND to operate in SLC mode and boosts performance and endurance as the write
amplification on the TLC NAND is minimized.
Dynamic Thermal Throttling
For PCIe SSD applications, when operation temperature increases, system CLK will decrease to protect the SSD and
controller with dynamic thermal throttling algorithm. The read/write speeds of the SSD will change at different temperature
levels in order to extend its lifespan.
Admin Command Register
The Admin command set is the commands that are submitted to the Admin Submission Queues. The detailed specifications
are described in NVM Express specification document.
